摘要： A system and method for calibrating integrated circuit (IC) temperature measurement circuits. An integrated circuit (IC) includes a thermal sensor and data processing circuitry. The IC may have a temperature measurement mode of operation and a calibration mode of operation. During the calibration mode, one or more stable reference voltages, rather than sensed voltages from a thermal sensor, are selected as input voltages to the data processing circuitry. Electronic components within the data processing circuitry receive the stable reference voltages and generate a temperature digital code. The generated temperature digital code may be compared to an expected temperature digital code based on theoretical ideal gains for each of the components within the data processing circuitry. The comparison leads to an updated value for a scaling factor to be stored and used in subsequent temperature measurements.

摘要： A system and method for measuring integrated circuit (IC) temperature. An integrated circuit (IC) includes a thermal sensor and data processing circuitry. The thermal sensor utilizes switched currents provided to a reference diode and a thermal diode. The ratios of the currents provided to each of these diodes may be chosen to provide a given delta value between the resulting sampled diode voltages. At a later time, a different ratio of currents may be provided to each of these diodes to provide a second given delta value between the resulting sampled diode voltages. A differential amplifier within the data processing circuitry may receive the analog sampled voltages and determine the delta values. Other components within the data processing circuitry may at least digitize and store one or both of the delta values. A difference between the digitized delta values may calculated and used to determine an IC temperature digitized code.

摘要： A method includes generating a first, second and third voltage output from a temperature sensing element of an integrated circuit using a respective, corresponding first, second and third, switched current source, for sequentially switching a respective first, second and third excitation current through the temperature sensing element. The third switched current source generates the corresponding third voltage output as a reference voltage between the first voltage and the second voltage. An error corrected difference is calculated between the first voltage and the second voltage using the reference voltage. In the method, the second excitation current is proportional to the first excitation current by a value n, and the third excitation current is proportional to the first excitation current by the square root of n.

摘要： A multiphase clock generating circuit includes a multiphase clock generator that produces a plurality of multiphase output signals at a first frequency and a multiphase divider with delayed reset control. The multiphase divider with delayed reset control is operatively coupled to receive the plurality of multiphase output signals at the first frequency and further operative to produce a plurality of multiphase output signals at a second frequency based on reset control information. As a result, an interface can be supplied with and switch between multiphase clock at different frequencies within a short amount of time with reduced power consumption and circuit area.

摘要： A device having a voltage mode driver with tunable amplitude and resistance that supports a predetermined output resistance and output amplitude is described herein. The voltage mode driver includes multiple configurable drivers. The voltage mode driver is controlled by a control module. Resistance tuning is controlled by the number of active configurable drivers and amplitude tuning is controlled by setting the high or low drive state of each active configurable driver. The slew rate of the device is controlled by delaying the setting of the high or low drive state of an active configurable driver by a predetermined interval.
